Limitations on scope of directions under articles 13 to 16
18.—(1) Without prejudice to articles 14(7), 15(7) and 17(4) of this Order, a direction shall not require or authorise any person to carry a firearm.
(2) A direction (except in so far as it requires any building or other works to be constructed, executed, altered, demolished or removed) shall not be construed as requiring or authorising the person to whom the direction was given, or any person acting as his employee or agent, to do anything which, apart from the direction, would constitute an act of violence; but nothing in this paragrah shall restrict the use of such force as is reasonable in the circumstances (whether at the instance of the person to whom the direction was given or otherwise) by a constable, or its use by any other person in the exercise of a power conferred by article 14(3) or 15(3) of this Order.
(3) In so far as a direction given to the Concessionaires or to any person mentioned in article 16(1)(c), (d) or (e) of this Order requires a building or other works to be constructed, executed, altered, demolished or removed on land outside the tunnel system, or requires any other measures to be taken on such land, the direction shall not confer on the person to whom it is given any rights as against a person having—
(a)an interest in that land, or
(b)a right to occupy that land, or
(c)a right restrictive of its use;
and accordingly, the direction shall not be construed as requiring the person to whom it is given to do anything which would be actionable at the suit or instance of a person having such interest or right in his capacity as a person having that interest or right.
(4) Nothing in this article shall be construed as derogating from any exemption or immunity of the Crown in relation to the provisions of this Part of the Order.
(5) In this article “direction” means a direction under article 13, 14, 15 or 16 of this Order.
